Remove or change reply-to address from autorespnder

I cant seem to change this email address to my business email or to a blank (no reply-to). I have followed instructions to leave this area blank but my personal email address keeps pops up in the autoresponders. I want to keep my private email address private from the autoresponders or have nothing there at all. How do I do this?

Based on my test the Reply-to Email cannot be blank. If you leave it blank it will pick up the account email address. However, you can use any other email address as the Reply-to Email.

Please try to change the Reply-to Email to your business email address again. If the issue is still not resolved, provide us a link of the form you are working on so that we can test it. 

Thank you for your reply. I tried that today but kept getting a warning.
Tonight I tried again but this time I was on mobile and everything went
fine and tested fine. Thanks again for your help.
